Connection structure of Ball valve of control valve for draining water out of water sink

The present invention relates to a water discharge of a water sink, and more particularly to a connection structure of a ball valve of control valve for discharging water out of the water sink to avoid a removal and a water leakage of the connection structure.

Referring to, a conventional connection structure of a ball valve of a control valve for draining water out of a water sink contains a Tee body A, and a filtration cap B, a positioning ring C and a ball valve D which are connected in the Tee body A. The Tee body A has a handle bar E configured to engage with the ball valve D. Thereby, the handle bar E is manually rotated to turn on/off the ball valve D, thus discharging wasted water out of the water sink.

The positioning ring C is fixed on the ball valve D. When the ball valve D is rotated to a recess D1, the filtration cap B is not flat to remove the handle bar E, and dirt in the water sink will remain in the positioning ring C or a slit. Also, the ball valve D, the positioning ring C, and the filtration cap B are connected in turn to cause troublesome connection, maintenance, and disconnection.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

The primary aspect of the present invention is to provide a connection structure of a ball valve of a control valve for draining water out of a water sink which is capable of avoiding a removal, an abrasion and water leakage and obtaining an easy connection.

To obtain above-mentioned aspect, a connection structure of a ball valve of a control valve provided by the present invention contains: a body, a filtration cap, the ball valve, a handle bar, and a positioning ring.

The body is a hollow tube, and the body includes a first connecting portion formed on a top thereof and configured to connect with the filtration cap, a second connecting portion formed on a bottom of the first connecting portion in a vertical direction of the body and configured to accommodate the ball valve, a coupling portion extending horizontally along the second connecting portion, and a fixing portion formed on a bottom of the second connecting portion.

The filtration cap includes multiple filtering orifices defined therein and configured to guide the wasted water into the body.

The ball valve is spherical and is received in the second connecting portion from a bottom of the body, wherein the ball valve includes a guide orifice passing therethrough, a connection portion extending along a horizontal direction of the guide orifice, wherein the handle bar is inserted into the coupling portion and connected with the connection portion so that the handle bar is engaged by the handle bar to be turned on/off.

The positioning ring is received in the fixing portion from the bottom of the body, and the ball valve includes a washers fixed between the ball valve and the positioning ring to avoid a water leakage of the body.

Preferably, the filtration cap does not contact with the positioning ring, and the ball valve and the positioning ring are received in the second connecting portion and the fixing portion from the bottom of the body.

Preferably, the body further includes a discharge orifice defined on an end thereof opposite to the coupling portion.

Preferably, the ball valve includes two washers fixed on a top and a bottom thereof.

Thereby, the connection structure of a ball valve has advantages as follows:

With reference to, a connection structure of a ball valve of a control valve for draining water out of a water sink according to a preferred embodiment of the present invention comprises: a body, a filtration cap, the ball valve, a handle bar, and a positioning ring.

The bodyis a hollow tube, and the bodyincludes a first connecting portion formed on a top thereof and configured to connect with the filtration cap, a second connecting portionformed on a bottom of the first connecting portionin a vertical direction of the bodyand configured to accommodate the ball valve, a coupling portionextending horizontally along the second connecting portion, and a fixing portionformed on a bottom of the second connecting portion.

Referring to, the bodyfurther includes a discharge orificedefined on an end thereof opposite to the coupling portionand configured to discharge wasted water, thus discharging water efficiently.

As shown in, the filtration capincludes multiple filtering orificesdefined therein and configured to guide the wasted water into the body.

As illustrated in, the ball valveis spherical and is received in the second connecting portionfrom a bottom of the body, wherein the ball valveincludes a guide orificepassing therethrough, a connection portionextending along a horizontal direction of the guide orifice, wherein the handle baris inserted into the coupling portionand connected with the connection portion, then the handle baris screwed by a screw so that the ball valveis engaged by the handle barto be turned on/off.

With reference to, the positioning ringis received in the fixing portionfrom the bottom of the body, and the ball valveincludes two washersfixed on a top and a bottom of the ball valve, thus avoiding a water leakage of the body.

Referring to, the filtration capdoes not contact with the positioning ringto cause an unflatness and a removal of the filtration cap. Also, the ball valveand the positioning ringare received in the second connecting portionand the fixing portionfrom the bottom of the body, thus connecting the ball valve, the positioning ringand the bodyeasily. Preferably, the ball valve, the positioning ringand the bodyare detachable easily to obtain easy maintenance, and the ball valveand the positioning ringdo not accommodate dirt.

Thereby, the connection structure of a ball valve has advantages as follows:
